Detailed answer

The time it takes for hyperpigmentation to fade varies from person to person and depends on various factors such as the severity of the hyperpigmentation, skin type, and the treatment used. In general, it can take anywhere between a few weeks to several months for hyperpigmentation to fade. Mild cases of hyperpigmentation may improve within a few weeks with the help of topical treatments such as topical creams containing ingredients like kojic acid or hydroquinone. However, more severe cases of hyperpigmentation, such as post-inflammatory hyperpigmentation or melasma, may take several months or even longer to fade completely. It is important to be patient and consistent with any prescribed treatment and to protect the skin from further sun damage by using sunscreen daily.
